` PERMUTATION-LOCK.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed January 13, 1919. Serial No. 270,895.

To all whom t may concern:

Be it known that I, MARK KosrcH, a subject of the Government ofMontenegro, residing at Washington in the District of Columbla, haveinvented certain new and useful Improvements in Permutation-Locks; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has for its principal object to provide a comparativelyslmple and inexpensive permutation or combination lock which will beparticularly well adapted for use upon safes and vaults, although it is,of course, also ap licable for other purposes.

A further o ject is to provide a lock in which a sliding handle isprovided for operating the bolt or bolts, and in which the locking ofsuch bolt or bolts is accomplished by lookin of said handle through theinstrumenta ity of permutation means housed therein.

With the foregoing in view, the invention resides in the novel featuresof construction and novel association of parts to be hereinafter fullydescribed and claimed, reference being made to the accompanying drawingwhich forms a part of this ap lication.

Figure l is an elevation of a oor equipped with the invention.

Fig. 2 is a horizontal section of the lock with parts in elevation,showing the relation of parts when the bolts are extended. y

Fig. 3 is approximately a duplicate of Fig. 2 but discloses the relationof parts when the bolts are retracted.

Fig. 4 is a vertical section the line 4 4 of Fig. 3.

Fig. 5 is an elevation of the permutation lock means, the handle beingbroken awayT and in section to illustrate such means.

Fig. 6 is a transverse section on the plane designated by the line 6-6of Fig. 4.

Fig. 7 is an end elevation of one of the tumblers.

Fi 8 is a detail section the line 8 8 of Fig. 7

Fig. 9 is a perspective view of one of the indicating rings with whichthe tumblers are equipped for properly positioning them to release thelock.

Briefly speaking, the lock consists of a hollow sliding handle H mountedon a door D or .other suitable Support. one or more on the plane of onthe plane of' bolts B carried by the door, connecting means C betweenthe handle and bolts for operating the latter from the former, lockmeans L for holding the handle against shifting, and adjusting means Awhereb the combination may be varied as require The door or the like Dis here shown as provided with four of the bolts B and the inner side ofsaid door is formed with channels 1 in which said bolts are mounted, aplate 2 being secured over said channels by screws or the like 3. Theseveral channels 1 open at their inner ends into a recess 4 formed inthe door D, said recess leading to the exterior of said door and beingby pref @rence of greater diameter at its inner end than at its outerend. The` handle H extends at its inner end into the recess 4 and theconnecting means C between said handle and the bolts B, are located insaid recess, said connecting means being herein shown in the form of onepiece links extendin diagonally from the handle tothe bjo ts, 1n suchmanner as to project said bolts when the handle is forced inwardly andto retract them when an outward pull is exerted on said handle.

For supporting the handle H, a post 5 is ixedly mounted on the door Dand extends outwardly from the recess 4, the inner end of said postbeing equipped with a cylindrical head 6 which is rotatable in anopening 7 in the door, this rotary mounting being provided in order thatthe post 5 may be turned to change the combination of the lock in amanner to be described. To normally hold the post 5 against rotation, apivoted arm 8 and La toothed ring 9 are provided. The arm 8 is pivotedat 10 to a plate 11 secured on the lnner end of the post 5, while thetoothed ring 9 surrounds the inner end of thepost and is secured byscrews or the like 12 to the inner side of the door. The arm 8 isadapted to engage any of the teeth of the ring 9 and it will thus beseen that dill'erent rotary adjustments of the post 5 may be made. Toretain the arm 8 1n engagement with the ring 9, a keeper 13 is provided,said keeper being shown in the form of a dished plate receiving the ring9, the arm 8, and the plate 11, screws or the like 14 bein employed fordetachably securing said eeper to the door so that it may be removedwhenever required to change the combination of the lock.

The Ahandle H is formed of an inner setq tion l5 and an outer section 16which is hollow throughout the greater part of its length. The section15 is provided with a bore 17 through which the post 5 extends and theouter cud of said section 15 is rcinovably received in the inner end ofthe hollow outer section 16, a screw or thc like 18 being provided forconnecting the two sections. iVhen the handle is forced inwardly toproject the bolts, the screw 18 is inaccessible, but when the handle iswithdrawn as in Fig. 4, the screw in question may be removed to permitdisassembling of the lock.

As one means of connecting the links C to the handle H, a collar 19 hasbeen shown surrounding the inner handle section 15 and clamped between ashoulder 2O on said section and the inner end of the outer scction 16.It will be understood that other means could be provided for connectingthe inner ends of the links C to the handle H.

The post 5 eXtendsthrougl-i the hollow portion of the outer handlesection 16 and is provided on its outer end with a removable head 21slidin in the bore 22 in the solid outer end or ob 23 of said handlesection, the portion of the post in the hollow part of the handle beingrovided with spaced lateral projections 2 suitably located.

Rotary tumblers 25 are mounted in the hollow handle section 16 and areby preference carried within a sleeve 26 which is secured by a screw orthe like 27 to the outer end of the handle section l5, said sleevehaving internal rings 28 which space the tumblers apart and hold themagainst shifting longitudinally of the handle. Each tumbler is providedwith an opening through which the post 5 passes and with a groove 29which may travel over the adjacent projection 24, when the severalgrooves are alined with their respective projections, thus permittingthe handle H to move outward f and retract the bolts B. When the handleis forced inwardly and the tumblers 25 rotated to move the grooves andprojections out of alinement, the handle is locked against movement onthe post 5 and consequently the lock cannot be released.

To render the tumblers 25 accessible for operation, one side of thesleeve 26 is cutaway as shown at 30, this cut-away portion registeringwith a similar slot 31 in the handle section 16, and if desired, anapertured plate 32 may be secured over the slot 31 as seen in Figs. 4and 6, the openings of said late and the slot in question being of sucient size to allow the fore-finger to be inserted for the purpose ofturning the tumblers.

In order that the tumblers may ,be roperly positioned, indicating rings35p 'are mounted thereon, und these rings are provided with projections3l, receivable in any one of a number ol' sockets. 35 with which thetumblers are jnovidiul. When the lock is disassembled, one or more ofthe projections 34: may be witlulrawn Afrom its socket and disposed inanother Iand by this means, it will be seen that a different churactermust appear at the opening of the plate 32, in order to properly sct thetuinblers YFor releasing the lock.

From the foregoing, taken in connection with the accompanying drawings,it will be seen that I have provided a pern'iutation lock of rathersimple and inexpensive nature, yet one which will be highly efficientand in every way desirable, the device being particularly well adaptedfor use upon safes and vaults. Since probably the best results areobtained from the details disclosed, they may well be followed, butwithin the scope of the invention as claimed, considerable latitude isallowed for making numerous changes in minor details. Furthermore, it isto be understood that the lock is applicable for numerous purposes andis not, therefore, restricted to use upon safes and the like.

What I claim is:

1. The combination with a closure and a bolt carried thereby; of ahollow handle eX- tending from said closure and bodily slidable inwardlyand outwardly, means actuated by the sliding action of said hollowhandle for operating said bolt, and means in said handle for locking thelatter against sliding.

2. he combination with a closure and a bolt carried thereby; of a hollowhandle extending from said closure and bodily slidable inwardly andoutwardly, means actuated by the sliding action of said hollow handlefor operating said bolt, and permutation means in said handle forlocking the latter against sliding.
